Questions
How big is the Gate pcb PCB?
It measures 63.9 × 40.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Gate pcb use?
33 parts, built around the ESP32-S3-WROOM-1-N8 and SUL6001S5-33. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Gate pcb KiCad files?
From the Lavapeeble/elec3117 repository on GitHub, at the commit this page was made from: the board is gate_pcb/gate_pcb/gate_pcb.kicad_pcb and its schematic Labs/Lab1_PCB/Lab1_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gate pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask Lavapeeble before reusing the design.
